Application led fune 28, 1922. Serial No. 521,415.

[y invention has to do with eye ,glass inountings, and it is my purpose to provide a mounting, having its parts so constructed and arranged as to reduce the likelihood oik breakage of the glass or lens supported by the mounting.

More particularly, it is Iny object to provlgle such a mounting having members tor engaging the lens or glass adapted to receive the lens between them, and lto be se-y cured thereto by means of a screw inserted through said members and the lens, which members are provided with flat-faced poi'- tions of substantial width, projecting` substantially away from said screws and adapted to grip the glass or lens, so as to prevent the breaking of the lens on the line of the screw hole therein.

TWith these and other objects in view, my invention consists in the construction, air rangement and combination of the various parts of my device, whereby the objects con te-inplated are attained, as hereinafter more fully set forth, pointed out in iny claim, and illustrated in the accompanying drawings, in which:

Figure 1 shows a iront elevation of a pair of eye glasses, having a mounting einbodying my invention.

Figure 2 shows a detailed, sectional view taken on the line 2-2 of Figure 1; and

Figure 3 shows a front elevation of a portion of the mounting, parts being broken away.

It is well-known that where the ordinary eye-glass inouiitings are used without rims for the lenses, the lenses frequently break on a line extending` across the screw hole therein. The screw hole is close to the edge of the lens, and so weakens the lens, that it is easily broken on such a line.

My purpose is to provide a mounting so constructed that the lens will not break on a line through the screw hole, but inust be broken on a line farther from the edge of the lens, so that a much greater body of the ,glass must be broken, and hence breaking will not occur so often, because it requires a greater strain to cause the lens to break when requipped with my mounting. i ln the accompanying; drawings, l have used the reference numeral 10 to indicate ,generally the bridge of an eye glass mounting of the rimless type. I D

Suitably supported are Frojecting` from the bridge ears or Qtraps 12, adjacent to which are the braces 18. of 'ordinary construction.

LMy mountinghas projecting from the straps or ears 12, the lugs 14e, which extend away troni the mountingsubstantial distances trom the mounting and are provided on their inner sui-faces withV tlat faces 15 adapted to engage the opposite sides of the lens or glass' 16.

The ears 12 are spaced from the lens 16 as illustrated at 17. i The earsl and lenses l@ are provided with suitable openines to receive the oidinai,V screw 18.. o

lt will be noted that the projecting' luUs or members 1111- have considerable beariiilf space and @reject from 'the mounting a suiiicient distance, so that there is no like lihood of breaking the eye :rif-isses on lines extended through the sci'e'w liolcs 19 therein. lnsoinueh` as eye glasses ordinarily break the guards 11. 1e the ordinary along the lines through the screws, the advantage of the lugs 14 will be obvious.

.ln actual tests, l have found that where my lugs are employed, much greater strain may be put on the lenses without brealino them, than can be done with the ordinary forms of mounting'.

lf claim my invention:

`The combination ci' lenses with an eve ,glass mounting, having; a bridge, nose guards, spaced ears spaced Jfrom the lenses, said ears having' lugs projecting` away from the mountingn provided with opposite llat faces forming bearings of substantial alignment toi.' engaging the lenses for substantial spaces, spaced from the screw holesof the lenses, said lenses and ears having screw holes, and screws received in said holes.
